The Project:

Trafikverket (previously Banverket) is

the authority responsible for rail and road

traffic in Sweden. Trafikverket tracks

market development and conducts re-

search and development in the railway

sector. It also advises Government on

railway issues. Moreover, Trafikverket is

responsible for the operation and man-

agement of state track installations,

they coordinate the local, regional and

interregional railway services and pro-

vide support for research and develop-

ment in the rail sector.

Trafikverket operates a 132 kV (trans-

mission) and 15 kV (catenary) network.

The 15 kV network is divided in 8 dis-

tribution areas.

PSI has been awarded the contract to

supply and install the new nation-wide

control center for Trafikverket. In the

first stage the eight formerly uncoupled

SCADA systems for electric supply ma-

nagement were replaced by one single

integrated system. In a second step, the

scalability of PSIcontrol was used to

integrate the supervision of a public

railway tunnel.

Project Objectives:

An important purpose of the new sys-

tem is to improve trouble detection and

removal.

As a result train service interruptions

are minimized and higher safety for the

maintenance personnel involved in

planned work is achieved.

Due to the distributed but integrated

system structure, personnel at different

locations can easily cooperate in case of

risky large scale disturbances.

As a result, single dispatch center evac-

uations (e.g. due to accidents) can be

tolerated, as the unique system archi-

tecture allows other centers to seam-

lessly take over operation.

PSIcontrol serves as nation-wide SCADA platform for electrical

supply management and infrastructure supervision.

One PSIcontrol system:- eight dispatch centers- better disturbance detection- higher safety- supervision of a public railway tunnel

The new system provides:

1. Secure power supply at

all times

2. Improved follow-up following dis-

ruption in train services

3. Higher reliability of data acquisi-

tion communication

4. Fast removal of disruptions

5. Improved safety of personnel

6. Reduced management costs

System Engineering:

To fulfill the high availability require-

ments of Trafikverket, the system is in-

stalled with a fourfold redundancy. Two

redundant central system components

are installed at two completely indepen-

dent locations.

The PSIcontrol system for Trafikver-

ket is designed to allow up to 50

concurrent operators and 25 mainte-

nance engineers to work in parallel.

The workplaces are installed in 8

different dispatch centers as well as

in the training center.

Highest availability due to multiple redundancies.

Specific Functions

For the purpose of railway catenary

segment switching, PSIcontrol pro-

vides sophisticated switching programs

especially developed for railway opera-

tors to speed up the switching process of

complex catenary systems.

It is possible to preselect complex

switching operations with one click.

PSIcontrol automatically selects the

best sequence to achieve the target

state without unwanted temporary

energization or deenergization of ad-

jacent segments. The result shows

the outcome of the switching opera-

tion in the online mode without ex-

ecuting the operation (preview

mode).

Training Simulator for the Railway Catanary System

The integrated dispatcher training

simulator (DTS) provides for a real-

istic environment for the education

of new dispatchers or for refresher

courses. In order to start a typical

training session, two or more regular

workplaces (otherwise used as dis-

patcher or data engineering work-

places) are started in trainer and

trainee mode, respectively. From

creating a single alarm to activating

complex disturbance scenarios, the

trainer has full control of the infor-

mation f low to all trainee workplaces.

With the help of PSIcontrol’s relay

toolkit, realistic system behavior can

be achieved (e.g. time-triggered au-

tomatic reenergization attempts,

modelling local hardware interlocks,

etc.)

Based on actual timetable the move-

ment of trains is simulated, which leads

to a realistic network load in the DTS.

Also, since the position of the trains on

the tracks is displayed, the trainee is

able to use a quasi-live system basically

indistinguishable from the real thing.

CityTunneln Malmö - Supervision and Control of a Public Railway Tunnel

Introduction

CityTunneln Malmö is a railway in-

frastructure project in southern

Sweden, which substantially im-

proves the public transport system in

the Öresund region (local area

around Malmö including the Öre-

sund bridge to Copenhagen, Den-

mark). At its core are two 6 km long

parallel railway tunnels below the

city of Malmö including three new

underground train stations.

PSIcontrol is used for the supervision

and control of the infrastructure. As

PSIcontrol is the top-level SCADA system for the tunnel supervision.

The integrated training simulator provides a

quasi-live system environment for

education.

Switching programs and target data preview

support the dispatcher in switching operations.

the top-level SCADA system it

monitors lower-level security systems

and acquires fire and fault alarms to

be sent to the Operations Manage-

ment Centre. The SCADA system

can also coordinate the control of

different actions, for example to en-

sure rapid response to accidents.

Supervised Infrastructure

The SCADA system controls several

technical subsystems like ventilation,

fire detection, fire water supply, etc. via

PSIcontrol’s HMI. Furthermore, all ele-

vators and escalators in the three new

train stations are supervised and the

operation status of the video cameras is

monitored.

In total the technical status of the

tunnel is monitored via the help of

~6500 binary indications and several

hundred analog signals. In the con-

trol direction there are ~600 double

commands towards technical subsy-

stem, which, in turn, control several

thousand devices (fans, pumps, val-

ves, illumination, door controls,

etc.).

Action Plans

In case of an emergency (e.g. fire alarm

or train accident) there is a need to lo-

cate the problem as precisely as possible

and to start appropriate actions quickly.

For this purpose the software package

ActionPlans has been developed which

helps the operator in selecting the cor-

rect rescue program and guides him

through the necessary steps. Roughly

20 action plans have been implemented,

which for any foreseeable critical situa-

tion in the tunnel or on the platforms

contain the appropriate actions. By

starting a particular action plan, speci-

fic commands are sent to technical

subsystems, which in turn trigger a se-

quence of actions. An example would

be to properly activate the ventilation

system in order to keep the platforms

free of smoke. Specific responses from

the process are displayed within the ac-

tion plan dialog which enables the ope-

rator to take further actions, if necessary.

Integration of Videostreams

An independent third-party video

system has been installed in the

tunnels and on the platforms which

maintains approximately 200 video

cameras. The corresponding video

streams are fully integrated within

the SCADA system, i.e. they are

part of PSIcontrol’s HMI. It is possi-

ble to switch between single and

quadruple stream depiction. Further-

more the cameras can be constrolled

(panning, zooming) via the interac-

tion with a video server.

Integrated video streams can show every place in the tunnel where an alarm might come up.

Support for correct decisions and quick actions

in a case of emergency.

Using PSIcontrol’s Drag&Drop phi-

losophy a specific video stream can

be accessed by simply dropping the

corresponding camera in the video

dialog.

The operator can select an individual

video camera out of any event/alarm

list to get the corresponding station

display selected.

As a typical PSIcontrol feature, by

clicking on an entry of an alarm/

event list, the operator can directly

access the corresponding station

display. In addition, by preselecting

the video mode, the operator can

also select from the alarm/event list

up to four associated video streams.
